invented certain new and useful Improve ments in Radiator-Caps, of,which the .following is a specificetio v Our invcntion'relates to a cu.or closure which is intended to replace e' ordinary plain radiator onused to close the water mlet of the radia r of an automobile, and isdesigned to perform certain useful functions in addition to that ofclosing the open 15 c afiditions the gasoline en 'ne of an .suto- It iswell known that under extreme Iuobile may become heat beyond a ointwithin'eontrol of the ordinary cspaei of the radiating systein, fromwhich a number of injurious and detrimental eflects result. In our novelradiator cap structure we hare rovided a forwardly directed ventilatornnel clesi ed to relieve the radiator of steam cause by the excessiveheat and to assist in coolin 1 tbe water in the radiator and this funneis capable of bein turned to a vertical position in which it is usefulas a water funnel when the suppl .of water in they radiator is beingreplenis ed. The object of our invention 18 the production of a.radiator cap having the structure and useful characteristics abovementioned, and

which shall be simple, acticsl, eflioient and desirable in constructionand arran out,

Thesmne letters of reference indicate the some parts in all the figuresof the drawings.

The base portion 1 of the base member of 1S screw-threaded to engage there lar rcaded opening of the radiator o the automobile upon which it isadopted to be used, and preferably is made t ght-fitting and formed ofresilient metal and slitted longitudinally, as shown, so that it will beheld ctiona-ll in any position to which it may be turner in the screwseat. Internally the base is formed with a recurved annular fie e 2which acts to defiect and turn back ownwardly any waves which may dashupwardly against the sides of the cap. Above the throat "formed by thisflange the body 3 of the base member is of a. hollow or bowl shapedform, the circular periphery of this body portion forming a seatinclined at an angle of 45 from the horizontal and being arran toreceive and rotatably engage the ouldercd base portion 4 of the funnel5, the oasis of which extends horizontally and the mouth of a whichopens forwardly when the funnel is inthel osition shown in Fig. 1 of thedraw- .he funnel member is yieldingly held upon its seat in rotatablerelation to-the base member by means of a screw bolt 6 which extendsaxially of the joint or seat ttbl pedf Sandroa a y engages e on orammousscreen member 7 made of elastic sheet metal. Preferably, and as shown,the bolt 6 makes screw-threaded enga. ment with an internally-threadedboss formed on the body '3, and a lock nut 9 is rovidccl to hold thebolt rigidly in place. ushers 9* are pro vided to relieve friction atthe pivotal engagement of the spring screen with the bolt, so that asmuch as possible of the frictional resistance to rotation of the funnelmember may be exhibited at 'thc circular joint between the, base andfunnel members.

.Pas of air through the Iu'nnel 5 is rem by means eta shutter device(see go. 1' end 2)., consisting of a circular plate 10 seated against ashoulder 11 formed n the neck of the funnel opening and held in place bya spring ring 12 engag ng c fi-oovc m such neck on the opposite side ofe plate, and. a, clrcular shutter 13 pivoted axially to said plate 10and equi d with n thumb-piece for tul'nin it. he plate Enid shuttermemberls afre (ill-1111,2111 in a. well own manner witi an-s it o 'ngsseparated by fun-shaped uncut poit izfis of the same or slightly greatersize, so that by rotation of the shutter the openings may be broughtinto registration, or may be close .I by adjacent uncut portions, asdesired.

It is obvious that when the automobile is traveling, with the ports inthe position shown in Fi 1 and the shutter open, air will be forceddownward into the m of the radiator, condensin the steam on cooling thewater and ding it vent through the overflow tube 14 of the radiatorstructure. Theshutter opening may be restricted as desired to modifythis action, or entirely closed, or the funnel opening may be turned tothe rear toprevent any cooling action. When it is desired to replenishthe radiator with water, the funnel may be rotated through on are of 180to bring it to the uprig t position shown in dotted lines in Fi 1, inorder that it may serve as a water innel.

In Figs. 3 and 4 we have shown a modilied form of construction in whichthe funnel member is secured to the base member in a different manner.In this modification the funnel member and base member are formedadjacent the joint between them with cross bars, marked 15 and 16respectively, which bars are pivotally connected at the axis of thejoint by a bolt 17, a ring washer 18 or other elastic member ing interin the pivot joint connection to yieldmgl restrain relative rotation ofthe can ports. With this construction the funnel will at all timesinduce a cooling action upon the contents of the radiator when directedforwardly.

In Fig. 5 we have illustrated another modification of our invention inwhich the funnel member is rotatably secured to the base member by ashort bolt assing through cross bars 15 and 16 on t two members, as inthe modification shown in Figs. 3 and 4 and alread described, and inwhich the funnel openmg is controlled through a cover plate 19 having aninner flanged stem 20 connected by a cmledspring 21 with the pivotedstructure. In the construction illustrated the spri is anchored to n lug22 on the bar 16. hen it is desired that air shall pass through thefunnel into the top of the radiator, this ca. may be drawn outwardly andthe lower rotated rearwsrdly so that the lower half of the cover platewill hook into the s ace between the funnel and base mcm ers of thedevice when the flmnel is in horizontal position in which 'tion it willbe retained by the tension 0 the connected spring.

In the modified forms of our device illustrated' in Figs; 3 to 5,inclusive, 9, screen 23 is preferably used just above the throat of thebase member to act as a strainerwhen the mdistor is being filled andalso serve to break up waves which may be thrown up against. theopening.
